Taking it out of the programmer's or manager's pay is ridiculous and probably illegal. You've never written code with a bug or two in it? If you want someone to right bug-free code or take financial responsibility for the code they've written, be ready to pay a lot more than you already do for that extra insurance.

It's a cost of doing business. I do think Amazon should reimburse the guy if only to save on negative publicity over a very small amount.
